    摘要： Improved .gamma.-alumina suitable for use as a catalyst carrier having high mechanical strength, a large specific surface area, and a substantially uniform pore size distribution in a relatively small portion of the pore size range below 500 A. Said alumina is produced by first establishing a seed aluminum hydroxide hydrogel having a pH of between 6 and 10 and then repetitively and sequentially adding an aluminum compound to adjust the pH to less than 5 or more than 11 to dissolve crystallites of aluminum hydroxide followed by addition of a neutralizing agent to return the hydrogel to the pH range from about 6 to 10 to cause pseudo-boehmite crystallites to grow. After a sufficient number of repetitions of said sequential addition, sparse aggregates of crystallites of the desired structure are formed. These are dried and calcined to produce the said alumina.

    摘要： A catalyst obtained by admixing red mud with alumina or/and an alumina-containing substance, optionally adjusting the water content of the admixture and/or adding an organic binder to the admixture, kneading and shaping the admixture into pellets having suitable size and shape, and calcining the pellets of 600.degree. C to 1,100.degree. C. The catalyst has a high compression strength and can, when used in the hydrodemetallization of hydrocarbons, achieve a high rate of demetallization and a low yield of low boiling fractions. The rate of demetallization is enhanced when the process is carried out using a hydrogen feed containing hydrogen sulfide.
